I am struggling too with making bracelets. I have found that the typical length for a bracelet for women is 7 1/2 inches and for men 8 - 8 1/2 inches. This said, it also depends on the size of the beads and the findings. I make the bracelet, then before I finish it off, I measure it, then check it on my wrist and then my daughter's. If it fits okay, I finish it and then take it with me to work and try it out on my boss and the other employee! I find that my bracelets with standard or smaller beads are great at 7 1/2 but if I use larger or longer beads, it can vary a lot! I hope someone out there can help!
